Example 2: Write Parameters (Multi-Parameter Request) - Siemens SINAMICS S120 Installation And Start-Up Manual

4.4.5

Example 2: write parameters (multi-parameter request)

Requirements
1. The PROFIBUS master has been commissioned and is fully operational.
2. PROFIBUS communication between master and slave is operational.
3. The master can read and write data sets in conformance with
PROFIBUS DPV1.
4. Control type: VECTOR
Task description
Jog 1 and 2 are to be set up for drive 2 via the input terminals of the Control Unit.
A parameter request is to be used to write the corresponding parameters as fol-
lows:
S BI: p1055 = r0722.4
S BI: p1056 = r0722.5
S p1058 = 300 rpm
S p1059 = 600 rpm
The request is to be handled using a request and response data block.
+24 V
Input in BI: p1055 and BI: p1056
